Final answer:
Regulation Z does not usually apply to real estate loans for a new business, as this falls under commercial loans, but it does cover real estate loans for single family homes, mortgage loan advertising, and car loans within a certain amount.
Step-by-step explanation:
Regulation Z, also known as the Truth in Lending Act, is designed to protect consumers by requiring full disclosure of the terms and costs of credit. In the context of the options provided, Regulation Z covers real estate loans for a single family home and mortgage loan advertising, but it does not generally apply to a real estate loan for a new business, as these are considered commercial loans and are exempt from these consumer protections.
Additionally, Regulation Z applies to loans up to a certain amount ($58,300 in 2021, which is adjusted annually for inflation), so it would cover a $24,000 car loan, as this falls within the consumer credit range.
